Hey hey :3 Thanks for your question!
I did upload a mac version of the male Kuro voice demo alongside the windows demo, but I've been informed that it doesn't work as it should :(
The big problem is that I don't own a mac myself and I also don't know anyone in person who has one, so I've got zero way of testing anything for mac which sucks >.< Heck, I didn't even know there was a way to run windows stuff on mac!
There's no proper demo out at the moment anyhow so you're not missing out on anything much :3 The old playable demo containing 2 routes was removed since it uses old art resources that I'm no longer including. The current demo is literally just a reel of voice clips from male Kuro's voice actor.
I'll definitely be attempting to release the full game on mac when it's ready, but I'm not sure if it will work T_T I followed the software's export instructions for the demo (which are pretty much identical to the export instructions for windows) and yet it apparently didn't work so I'll probably need to find some help as to why exporting the project to mac isn't working correctly. I'll also be trying to release it in app form, but that will take some extra time after the PC release as it requires me to change some of the file formats and stuff.
I'm glad to hear that you're interested in the game though, it means a lot to me! :3 I shall try my best when it's ready for full release to get it working on as many platforms as possible :D
